网络通信记录分析系统在数字化变电站中的应用

在数字化变电站中,过程总线将替代电缆硬连接用于模拟量、状态量和跳闸信号的传输.为了便于运行和维护,有必要对数字化变电站的通信过程进行记录和分析.文中以一套实际系统为例,对网络通信记录仪和分析仪实现的关键技术进行了分析,涉及通信在线分析和大数据量存储等;该系统通过采用特殊设计的智能网卡,提高了网卡吞吐量,从而提高了记录仪可接入的合并单元数量.文中还对网络记录分析系统未来的发展趋势进行了预测.

Application of Network Communication Recorder and Analyzer in Digital Substations

In digital substations,the hard-wired cables are replaced by the process bus for the transmission of AC signals,status signals and tripping signals based on the fiber-optic network. It is necessary to record and analyze the network communication process for the operation and maintenance of digital substations. An actual system is taken as an example to analyze the key techniques of the communication recorder and analyzer involving the communication on-line analysis and large amount of data storage.
